Boundary-scan (1149.1) technology was originally developed to provide a far easier method to perform digital DC testing to detect intra-IC interconnect assembly faults, such as solder shorts and opens. Today�s advanced IC technology now includes high-speed differential interfaces that include AC or DC coupling components loaded on the printed circuit assembly. Simple stuck-at-high/low test methods are not sufficient to detect all assembly fault conditions, which includes shorts, opens and missing components. Improved diagnostics requires detailed circuit analysis, predictive assembly fault simulation and more complex testing to isolate and accurately detect all possible assembly faults.

We've lost a close industry friend in Glenn Seely. Glenn worked for SMTnet a few years ago and we all enjoyed working with him. Glenn was truly a really nice guy who oftentimes had a wonderful smile on his face, just like in the photo we have in this article.
A memorial for Glenn was held in Nebraska on Saturday, February 9 and another will be held on Sunday, February 17 in Lago Vista, TX. A memorial account has been set up for Glenn�s family and to help defray medical costs:

Thank you Glenn from the entire SMTnet team. We will miss you but not forget you.
